I bought one pair about a year (give or take) ago and they are still doing great for me. I only wear glasses when I don't have my contacts in and, I must say, it was a steal to get a good pair so cheap. I paid around $20 for the ones I bought from Zenni and they are just as good as a pair I bought a year before that for over $100.

My sister bought a pair a few months after I bought mine and hers are still holding up great, too. And she wears hers much more than I do.

I just want to give a big Thank you to whoever first suggested Zenni Optical.
